I am having a hard time concentrating...

Just finished a 2500 word essay that came out at 8000, but was told that appendix information did not count towards real word count, so it still feels like I got carried away and I have small bit of sheer terror in pit of stomach; cos its sheer, it is not as substantial. I am not made of the stuff that others are, and everyone knows it. Time is making me distintegrate.
